Problems solved by technology

[0002] At present, the extreme pressure agents of lubricating grease are usually sulfur-containing compounds (such as sulfurized olefins, sulfurized lard, sulfurized oleic acid, polysulfides), phosphorus-containing compounds (such as phosphates, phosphites, phosphates) and nanomaterials. , and sulfur-containing compounds and phosphorus-containing compounds have the disadvantages of strong irritation and strong corrosion when they are used as extreme pressure agents for grease; in addition, when liquid metal is directly used as a lubricant, the cost is high, and under low load conditions Poor wear resistance

Embodiment 1

[0042] Take 98g of grease base, add 0.5g of antioxidant 2,6-di-tert-butyl-p-cresol, 1g of anti-wear agent diethyl phosphate amine salt, 0.5g of pure gallium, heat to 90°C and stir for 30min until uniform, cool to room temperature, transferred to a three-roll mill and ground for 3-5 hours to obtain sample 1.

Embodiment 2

[0044] Take 98g of grease matrix, add 0.5g of antioxidant 2,6-di-tert-butyl-p-cresol, 1g of anti-wear agent diethyl phosphate amine salt, 0.5g of a mixture containing 75 parts by weight of gallium and 25 parts by weight of indium, Heat to 90°C and stir for 30min until uniform, transfer to a three-roll mill and grind for 3-5h uniformly, cool to room temperature to obtain sample 2.

Embodiment 3

[0046] Take 98g of grease base, add 0.5g of antioxidant 2,6-di-tert-butyl-p-cresol, 1g of anti-wear agent diethyl phosphate amine salt, containing 64 parts by weight of gallium, 24 parts by weight of indium and 12 parts by weight of tin 0.5 g of the mixture was heated to 90°C and stirred for 30 min until uniform, cooled to room temperature, transferred to a three-roll mill and ground for 3-5 h to obtain sample 3.

Abstract

The invention provides lubricating grease and a preparation method thereof. The lubricating grease comprises a lubricating grease matrix and a gallium-based liquid metal. The grease is non-toxic, non-irritating and non-corrosive, and can achieve excellent extreme pressure performance comparable to that of gallium-based liquid metal under high load conditions, while the cost can be reduced to less than one tenth of that of gallium-based liquid metal. And the anti-wear performance under low-load conditions is significantly better than that of gallium-based liquid metals, and is suitable for various working conditions from low loads to high loads.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to lubricating grease and a preparation method thereof. Background technique [0002] At present, the extreme pressure agents of lubricating grease are usually sulfur-containing compounds (such as sulfurized olefins, sulfurized lard, sulfurized oleic acid, polysulfides), phosphorus-containing compounds (such as phosphate esters, phosphite esters, phosphates) and nanomaterials. , and sulfur-containing compounds and phosphorus-containing compounds have the disadvantages of strong irritation and strong corrosion when they are used as extreme pressure agents for grease; in addition, when liquid metal is directly used as a lubricant, the cost is high, and under low load conditions Poor wear resistance. [0003] Therefore, the relevant technology of existing lubricating grease still needs to be improved. Contents of the invention [0004] The present invention aims to solve one of...
